2 SHEETS-SHEET 2- UNFFFD Uillrtflfm PATENT WILLIAM H. ALBEE, OF MARLBORO, MASSACHUSETTS.

HEEL-BREASTING MACHINE.

Appli-cation lefl November 6, 1915.

T all whom t may concern Be it known that I, WILLIAM H. Amann, a citizen of 'the United States, residing at Marlboro, in the county of Middlesex, in the State of Massachusetts, have invented a certain new and useful improvement in Heel-Breasting Machines, of which the fol lowing is a specification, reference being had to the accompanying drawings.

This invention relates to heel breasting machines and more particularly to means for guiding the heel to be breasted under the cutter and afterward removing the breasting chip from the path of said cutter and the object of my invention is to provide suitable means to guide the heel into proper position under the cutter and, after the cutting operation, remove the breasting chip.

Vith this and other objects in view, my invention consists in certain novel devices, combinations, and arrangements of parts, as will be hereinafter described and more specifically pointed out in the appended claims.

In the accompanying drawings, l have illustrated my improvement sufliciently to enable those skilled in the art to understand the construction and operation thereof.

Referring to the drawing, Figure 1 is a side view of certain of the parts of my heel breasting machine.

Fig. 2 is an end View partly in section of Fig. 1 looking in the opposite direction of arrow t on Fig. 1. Fig. 3 is a plan view of my machine with the cutting mechanism omitted.

Fig. 4 is a similar view of the same, showing the plungers engaging the breasting chip.

In the accompanying drawing 1() is the base portion of the main stand having an upright bearing 11 in which is loosely mounted the shaft portion 12 of the cutterholder plate 13.

A spring 1li encircles the shaft 12 and abuts at one end, the bearing 11. The other end of said spring 111 has its bearing under the fiange portion 12a of the shaft 12.

The spring 14 acts to retain the cutterhold plate 13 in its upper position (Fig. 1).

15 is the cutter and is preferably of curved contour. Said cutter is secured to the holder' plate 13 by means of a screw 16.

Adjustably secured to the base portion 10, by bolts 1'?, is a U shaped. member 18 to Specification of Letters Patent.

which is adjustably secured, by bolts 19,

stands 20, each stand 2O having a cylindrical portion 21. with an opening 22 therein.

Loosely mounted within the portion 214 of each stand is a plunger 23; said plunger having an enlarged portion 2i with an opening 25 therethrough.

A spring 23 encircles the portion 23 of the plunger 23 and has a bearing at one end against the enlarged portion 2t of said plunger 23. rl"he opposite end of the spring 2G has its bearing against the inner end of the cylindrical portion 21. Said spring 2G acts to force the plunger 23 inwardly; the inward movement being however limited by means of a nut 2T on the portion 23 of the plunger 23.

28 is a wood block secured to the member 18 by screws 29.

30 is the heel to be breasted and is guided into proper position transversely by means of a guide plate 31 adjustably secured to the member 18 by bolts 32.

Heel 30 is retained in proper longitudinal position by plungers 23, (see Fig.

lf will now briefiy describe the operation of the above mechanism.

The heel is first placed by the operator on the bloclr 28 under, and in the path of, the cutting knife 15.

The cutter is then forced downwardly into the heel (Fig. 2), by means of a cam or other suitable mechanism (not sho-wn) operating on the flange portion 12a of the shaft 12.

With the downward movement of the cutter 15 the plungers 23 are forced outwardly by means of plungers 33 adjustably secured to the plate 13.

The lower end of said plungers 33 enters through the opening 22 in the cylindrical portion 21 of the stand 20, engages the slotted portion 24C of the plunger 23 and forces said plunger outwardly, (see Fig. 2).

After the cutter has completed this operation, the spring 14 encircling the shaft 12 will cause the cutter 15 to he carried upwardly, together with the plungers 33, to normal position, the plungers 33, thus releasing the plungers 23, allowing them to engage the breasting chip (Fig. t) thus providing for the discharge of said chip through an opening in the base 10, into a suitable receptacle.

Having thus described my invention, it will be evident many changes and modif-hre.dn

and supporting a heel in the path of the knife, laterally movable plungers, means for automatically holding said plungers in abutment with the heel, and additional 've- 1"- tically movable plungers cooperating with said laterally movable plungers for withdrawing said laterally movable plungers from such abutment with the heel during the heel-cutting operation, said laterally movable plungers, during the upward move ment of said vertically movable plungers, beingforced by the action of their autoautomatically holding said plungers in abutment with the heel, each plunger' having `a1 vertical passage therethrough with one wall of said passage inclined downwardly to'- ward the opposite wall thereof, `and/additional plungers for effecting'the withdrawal of said laterally movable plungers vfrom such abutment with the heel during the heeleutting operation, said additional plungers each having a beveled lower end engaging the'inelined passage wall ofeach of the first-referred to plungers.`
